Detailed Description

a backend is chosen at runtime from the scheme of the url, which is why this is a virtual interface rather than a concept the way the codecs do it: the answer is in a config file, not in the build.

◆ get()

virtual boost::asio::awaitable< std::optional< CacheEntry > > Haio::Cdn::CacheStore::get ( const std::string & key )

pure virtual

a hit renews the entry's ttl, so what is being asked for keeps living and what nobody wants ages out. the window is therefore since the last read, not since the write: a popular creative is never rebuilt on a clock.

◆ put()

virtual boost::asio::awaitable< void > Haio::Cdn::CacheStore::put	(	const std::string &	key,
		const CacheEntry &	entry )
